KEY-OPENING CAN.

SPECIFICATION forming part of Letters Patent No. 665,456, dated June '7, 1898. Application filed September 10, 1894. Renewed June 26, 1897. Serial No. 642,528. (No model.)

T0 on whom it may concern.-

Be it known that I, EDWARD BARRATH, a citizen of the United States, residing at Ohicago, in the county of Cook and State of 1111- nois, have invented a certain new and useful Improvement in Key-Opening Cans, (Case No. 9,) of which the following is a full, clear, concise, andexact description, reference being had to the accompanying drawings, form ing apart of this specification.

My invention relates to key-opening cans; and its object is to provide a can adapted to be opened by tearing away the rim of the can-cover.

My invention comprises a can-body provided with an oblique flange and a cover provided with an oblique rim extending upward and outward adapted to rest upon said flange, a circumferential line of reduced strengthbeing provided upon said rim, said line of reduced strength and the edge of the rim'terminating in a free lip adapted to be grasped to remove the rim and permit access tothe interior of the can.

Referring to the accompanying drawings,

Figure 1 is asectional view of a can embodying my invention. Fig. 2 is an elevation of Fig. 3 is a sectional View of a modified form. Fig. 4 is an elevation of the same. Figs. 5 and 6 are views of keys employed in opening the cans. Fig. 7 is a sectional View of a modified form of cover.

Like letters refer to like parts throughout the different figures.

Referring'to Figs. 1 and 2, the can-body a is provided with an oblique flange a, extending upward and outward, a ridge a being thrown out just beneath the flange. The cover I) is provided with an oblique'rim 1), extending upward and outward and adapted to rest upon the flange a. Between the rim 1) and the face 12 of the cover an offset is provided.- A line of reduced strength 0 extends circumferentially about the cover and is joined by the oblique line of reduced strength 0 with one edge of the free lip d, the other edge of which forms a continuation of the edge of the rim. When it is desired to re-.

move the cover, the free lip is grasped with a key and the rim b torn away, thus freeing the face of the cover and permitting its removal. The ridge a is formedjust beneath the can-body and the face of the cover of solder, whichwould thus bind theface of the cover and the body of the can together after the rim had been removed. In Figs. 3 and f the flange on the body of the can extends inward instead of outward.

The offset in the cover is provided so that a key e, such as that illustrated in Fig. 5, may be employed, the slot 6 being not extended to the end of the key and the offset affording room for. the travel of the metal at the end of the key. If a key such as that of Fig. 6 be employed, it will not be necessary to provide the offset, though preferable,

and a cover such as that shown in Fig. 7

can provided with a cover having an oblique rim extending about the same, the oblique rim being adapted to be torn away by means of. a free lip. The claims of the present case relate to a specific form of the general invention inwhieh the oblique rim upon the cover extends upward and outward.

In applications, Serial No. 522,666, filed September 10, 1894, and Serial No. 53l,335,

of a can provided with an oblique flange, of

a cover provided with an oblique rim extending upward and outward, a circumferential line of reduced strength extending about said rim and a free lip adapted to be grasped to tear the cover along said line of reduced strength, substantially as described.

Ice

lines of reduced strength, substantially as [0 described.

In witness whereof I hereunto subscribe my name this 8th day of September, A. D. 1894.

EDWARD BARRATH.
